What should I do if the three-way catalytic converter is damaged?
1 Answers
The three-way catalytic converter is damaged and should be replaced immediately with a new one. Below is an introduction to the three-way catalytic converter: Function: The three-way catalytic converter is a component in the car's exhaust pipe that purifies the exhaust gases. Without it, the harmful substances in the car's exhaust would exceed the standard. The car's exhaust pipe consists of three parts: the front section, the middle section, and the rear section. Installation: The car is equipped with a three-way catalytic converter and an oxygen sensor device, which can convert harmful gases such as CO, HC, and NOx in the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Data Provision: If the three-way catalytic converter is damaged, the second-stage oxygen sensor will not be able to correctly provide data to the car's computer, leading to either too lean or too rich a mixture concentration. A too lean mixture can cause ignition difficulties, weak driving, engine backfiring, etc., while a too rich mixture can increase fuel consumption, incomplete combustion, and severe carbon buildup in the cylinders and spark plugs. When such faults occur, the engine fault light should illuminate.
